The finding of the enigmatic pathogen Anisolpidium rosenvingei in the filamentous brown macroalga Pylaiella littoralis presented a unique opportunity to histochemically study the distribution of chitin in this little-known pathogen using FUNGALASE™-F, a fluorescein-labelled chitinase. Chitin was found localised to the exit tube of this pathogen, which infects exclusively reproductive cells of its host. The cytological and phylogenetic implications of this finding are discussed. This paper also reports the first record of this pathogen in the United Kingdom, on the west coast of Scotland.
